' BAKING AN i vThis invention. relatestorbaking pans, and

yhas forits objectthe production ofkv a panin Which materials, such asfcakes,A etc.,may be baked Without the creation of a crust on thek sides lor edges thereof.y

`With the aboveand other objects in view, -as Will be apparent, this invention consists ent inventionz, f .Y A e Fig. 2 'is aV longitudinal ivertical section rtaken along line 2,*2 of Figi; andf y "5 Figli is an enlarged verticalfragmentary Y section'taken along line 3-'3 ofy Fig.r2.

lHeretoforesuch cakes have been baked without effort to eliminate the'` crusts on 1 .the kedges thereof, with the resultthat after 145 the baking'operation is completed it is frequently lnecessary to-` trim f the edges of ythe cake vslabto remove thecrusts, this being true lof slabs to beV used .in jellyj f rvbead 12.
